Abstract

Die Erfindung bezieht sich auf ein Verfahren zur Signalverarbeitung und Signalprozessierung nach dem ROSAR-System, das eine Lösung aufzeigt, wie Elevationsinformationen hoher Auflösung mit einer feststehenden Sendeantenne ohne Drehkreuz erhalten werden können. Die Elevationsinformationen werden dadurch gewonnen, dass von einer teleskopartig ausfahrbaren Sendeantenne mit großer Vertikalabmessung die abzubildende Umgebung fächerartig beleuchtet wird und dadurch entstehen übereinanderliegende Sektoren in Elevation. Ein Ausführungsbeispiel ist erläutert.

Figure 00000001
The invention relates to a method for signal processing and signal processing according to the ROSAR system, which shows a solution as to how high-resolution elevation information can be obtained with a fixed transmission antenna without a turnstile. The elevation information is obtained in that the area to be imaged is illuminated in a fan-like manner by a telescopically extendable transmitting antenna with a large vertical dimension, and this results in superimposed sectors in elevation. An embodiment is explained.
